Abstract

An optical arrangement includes an optics holder and a reflective optic fixed to the optics holder, in which the optics holder includes at least two holding members for fixing the reflective optic to the optics holder, and in which at least one of the holding members is resiliently deflectable.

Claims

1. An optical arrangement comprising:

an optics holder; and

a reflective optic fixed to the optics holder, wherein the optics holder comprises at least two holding members for fixing the reflective optic to the optics holder, at least one of the holding members being resiliently deflectable.

2. The optical arrangement according to claim 1, wherein each of the at least two holding members comprises a holding arm and a holding face for receiving the reflective optic, the holding face being arranged at an end of the holding arm.

3. The optical arrangement according to claim 2, wherein each holding arm comprises a corresponding longitudinal axis extending along an elongated portion of the holding arm, and the plurality of longitudinal axes are arranged equidistantly with respect to an axis extending perpendicularly to a reflective surface of the reflective optic.

4. The optical arrangement according to claim 2, wherein each holding face comprises a circular end of the holding arm on which the holding face is arranged.

5. The optical arrangement according to claim 2, wherein each holding face is deflectable along a direction that is parallel to a reflective surface of the reflective optic or is deflectable tangentially with respect to a rear side of the optic.

6. The optical arrangement according to claim 2, wherein the holding faces are arranged rotationally symmetrically with respect to an axis extending perpendicularly to a reflective surface of the reflective optics.

7. The optical arrangement according to claim 1, wherein all the holding members of the optics holder are resiliently deflectable.

8. The optical arrangement according to claim 1, wherein one of the at least two holding members comprises a fixed, non-resilient support body having a support face to which the reflective optic is fixed.

9. The optical arrangement according to claim 8, wherein the resiliently deflectable holding members are arranged symmetrically around a center region, and the support body is arranged at the center region.

10. The optical arrangement according to claim 1, wherein a rear surface of the reflective optic is fixed to the holding faces, wherein the rear surface is opposite from a reflective surface of the reflective optic.

11. The optical arrangement according claim 1, wherein the reflective optic is fixed by an adhesive to the holding faces.

12. The optical arrangement according to claim 1, wherein the optics holder comprises at least three resiliently deflectable holding members.

13. The optical arrangement according to claim 1, wherein the optics holder is formed of an aluminum alloy.

14. The optical element arrangement according to claim 1, wherein the optics holder is formed as one piece.
